Motion from Color

摘要

The use of color images for motion estimation is investigated in this work. Beyond the straightforward approach of using the color components as separate images of the same scene, a new method, based on exploiting color invariance under motion, is discussed. Two different sets of color-related, locally computable motion “invariants” are analyzed and tested in this paper, and the results of motion estimation based on them are compared to the direct use of the RGB brightness functions.
